Final answer:
Destruction of the amygdala would predominantly impact the expression of emotional feelings, as the amygdala is crucial for processing and expressing emotions, especially fear and anxiety.
Step-by-step explanation:
The destruction of the amygdala would mostly affect the expression of emotional feelings. The amygdala, a nucleus deep in the temporal lobe of the cerebrum, plays a critical role in emotions, particularly fear and anxiety. It is involved in emotional processing, attaching emotional value to learning processes and memory, and facilitates encoding memories at a deeper level when the event is emotionally arousing. Damage to the amygdala would affect how emotional responses are processed and expressed, which could lead to significant changes in a person's behavior and emotional experiences.
